Three-factor models of narcissism (Agentic, Neurotic, and Antagonistic Narcissism) have gained widespread recognition in the field. The Five-Factor Narcissism Inventory (FFNI) stands out as the most comprehensive and only tool to date that assesses all three narcissism domains. However, its validation in Chinese culture and forensic contexts remains largely unexplored. With community (N = 578) and offender (N = 726) samples from China, we examined 60-, 30-, and 15-item versions of the Chinese FFNI in terms of internal structure, external associates, and consistency across samples and versions. Our findings demonstrate acceptable internal consistencies and structural validity of each version of the Chinese FFNI, albeit with minor deviations in the Neurotic Narcissism factor. The FFNI demonstrated good cross-sample and cross-version consistency. These results suggest the utility of the FFNI in Chinese samples and suggest some comparability across community and offender groups. (PsycInfo Database Record (c) 2024 APA, all rights reserved).
